ence marked thereon, which form a part of this specication.

This invention relates to improvements in combined horseshoes and padsof that class commonly known as a tip or threequarter shoe which isfitted to a pad, the: shoe receiving the weight brought upon the j toeor front part of the horses foot and the 3 pad being located beneath andprotecting the A tender part of the foot. The invention relates also toa novel form of shoe or tip for use with pads.

Among the objects of-our invention is tol provide a combined horseshoeand pad wherein the shoe is provided with a plurality of calks soarranged that the forwardmost calk or calks of the series andtheyielding or active portion of the pad first .come into contact with theroadway in the beginning of the use of the shoe and receive the firstwear brought thereon and the other calks in rear of the forwa-rdmostcalk or .cal-ks are brought successively into active relation withrespect to the roadway as the calk or calks in ad Vance thereof are wornaway. As a result of this `construction the life of the shoe is greatlyprolonged over that of a shoe having .a like number of calks which areadapted to be brought simultaneously into active relation with respecttothe roadway when the shoe is first used. In the latter constructionthe life of the shoe is but little greater than the effective life of asingle calk, while in our construction the action of the series of calksis cumulative and the period of effective use of the shoe is thereforegreatly prolonged.

-In the drawings, Figure l is a bottom plan view of a combined shoe andpad containing the improvements constituting our invention. Fig. 2 is alongitudinal section on line 2 2 of Fig. 1. Fig. 3 is a bottom plan Viewof a fragment of one of the rear ends of the shoe, showing amodification. Fig. 4 is a similar view showing a further modification.Fig. 5 isa transverse section on line 5 5 of Fig. 2.

As shown in the drawings, A designates the body ofthe shoe, and B thepad, the latter consisting of a leather base B', shaped to fit the footof a horse, and a formed mass of rubberBz, attached to the under surfaceof the leather base bystitches in4 the manner shown and constituting theactive portion of thepad.

The shoe as herein shown is provided on its under side with sevenholding-calks, one, A', at the toe of the 'shoe centrally thereof andthree, A2, on each side, the calks at the sides bel ing arranged inthree opposite pairs between 4the toe-calk and the pad. The calk at thefront are arranged transversely of the body of the lshoe.

The body of the shoe is 4desirably made thickest at the toevof'thehshoeand tapers from the' thickest part to its rear end, where it is joined`to the pad. Thecalks are made of gradually-increasing depth from thefront to the rear calks, said lrear ealks being the longest and thetoe-calk shortest. The length of theseveral calks is shown as soproportioned, however, with respect to their location on the taperedbody of the shoe that the depth of the shoe as a whole is the same inall parts thereof. When the shoe is iitted to the'pad, the depth of thepad is such as to cause the shoe when resting on a supporting-surface tobe supported on the pad and on the front or toe calk. When pressure isbrought to bear upon the shoe, as by the weight of a horse, the calksnext in rear of the toe-calk may have contact with the su p porting-surface to give lateral stability to the shoe; but no considerable weightis transmitted thereto until the front calk has partially worn away, at'which time the said calks next in rear of the toe-calk'are brought intoaction. The several pairs of calks are in this manner made to assumeoperative relation to the roadway until all the calks have been broughtinto action.

Desirably the calks are made gradually thinner from the front to therear of the shoe, whereby the calks which are vthe last to be broughtinto action are made of such width that they will be at all timesequivalent to sharp calks even when worn down considerably. Moreover,the thickening of the front cal k or calks, which receive the greatestwear in the life of the shoe, serves to increase the durability of theshoe. Furthermore, the thickening of the body of the shoe at the toethereof strengthens the shoe where it is subject to the severest strainsand at the same time serves to properly balance the shoe without addingundue weight thereto. A further advantage of thickening the shoe at thetoe thereof and making the calks of gradually-increasing depth fromfront to rear of the series is that, in addition to the strengthening ofthe shoe at the toe and the proportioning of the metal so as to properlybalance the shoe, the life of the rear calks, which are the last to bebrought into use, is thereby prolonged, and as the shoe is effective solong as the rear ealks are active the life of the shoe as a whole isthereby greatly prolonged. Obviously if the body of the shoe be made ofthe same thickness throughout the rear calks, or those in rear of thetoe-calk, would need to be made more shallow, thereby shortening theireffective life and the life of the shoe.

Desirably the front calk is reinforced by two calks A3, located in rearof the same and at the ends thereof. Said calks are shown as circular incross-section and taper from their bases to their outer or bearing ends,but may be made of other form. The auxiliary calks A3 serve to relievethe front calk A, upon which the severest wear and strain are brought,and thereby lengthen the life of said front calk. Moreover, saidauxiliary calks A3 being made sharper than the front calk aid to holdthe toe of the shoe from slipping after the front or toe calk isconsiderably Worn.

The clip Alof the shoeis horizontally rounded or convex on its innersurface, as indicated in Fig. 5. The purpose of so forming said clipisto enable the same to beset more closely into the notch of the foot cuttherein by the farriers knife when the shoe is being fitted. In practicesuch notch so made in the hoof is concave, and the convex inner face ofsaid clip fits the concave notch more perfectly than a clip having asquare or dat inner surface. In Fig. 3 the rearmost calk A5 is shown asmade of curved or corrugated form and extending generally longitudinallyof the body of the shoe. Said calk begins at or near the secondnail-hole from the rear of the shoe and extends past the rearmost holeand is curved around said rearmost nail-hole to permit ample room fordriving the rear nail. In Fig. 4 the' rearmost calk A is made straightand disposed longitudinally of the end of the body of the shoe. Bothforms of the rear calks (shownin Figs. 3 and 4) will be made somewhatdeeper at their rear than at their front ends to bring the edges thereofgenerally parallel with the lower or holding edges of the calks in frontofthe same. Said longitudinally-arl ranged calks A5 and AG act whenbrought into use to prevent slipping of the shoe sidewise, and the formof the calk A5 serves also to prevent slipping of the shoe from front torear.

Otherchanges in the structural details herein illustrated maybe madeWithout departing from the spirit of our invention, and we do not wishto be limited to such details except as hereinafter made the subject ofspecific claims.
